Infantile Hypertrophic Pyloric Stenosis Surgery versus Nutritional Therapy

Methods: Thirty-eight IHPS patients were enrolled in the study and subdivided into surgical (22 patients) and nutritional groups (16 patients). Surgery involved extramucosal pyloromyotomy, while nutritional therapy consisted of small and frequent meals only. Patients were monitored both clinically and with ultrasound. A long-term follow-up 13-19 years after treatment was carried out to investigate gastric emptying function. Patients were assessed by ultrasound to evaluate gastric volume and emptying time.
